# CarryMap vs GTField GPS & Data collection

The clearest difference is in-app purchases: CarryMap at none against GTField GPS & Data collection's 3. CarryMap also leads on ratings volume (299 vs 4) and review sentiment (80% vs 60%). GTField GPS & Data collection's advantage is update cadence (every 3 weeks vs every 4 months) and rating (5.0 vs 4.6). On price, ads and device support there is nothing between them.

Both are free to download. GTField GPS & Data collection sells 3 in-app purchases, starting at $9.99 per month. CarryMap asks for nothing beyond the download.

GTField GPS & Data collection holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: CarryMap has 299 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 80% of CarryMap's written reviews are positive against 60% of GTField GPS & Data collection's, so the app with the better star average is not the one people write more warmly about.

CarryMap ships an update every 4 months, GTField GPS & Data collection every 3 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
